Research shows cover crops benefit wildlife, farmers alike

For Release: June 5, 2015

NWF sponsors agriculture research demonstrating wide range of benefits

Washington, DC (June 5, 2015) – Sustainable agriculture practices have many benefits such as reducing erosion and protecting water quality. But they also support a stronger economy and healthier ecosystems. Since 2013, NWF has been supporting research that further demonstrates the wide range of benefits from sustainable agriculture, particularly cover crops.

NWF awarded grants to researchers from Iowa State University and Western Illinois University to assess and interpret the economic impacts of using cover crops such as reduced input costs at the farmer level to job creation at the economy-wide level. Researchers from University of Missouri and St. Joseph’s College explored the wildlife habitat values of cover crops such as nesting numbers and success, incidence of trap habitat, forage ability and pollinator support.

“We know about the water quality benefits of cover crops, reducing field nutrient runoff by up to 90 percent,” said Ryan Stockwell, Senior Agriculture Program Manager for NWF. “However, one area lacking a solid body of knowledge is the upside for wildlife like the nesting and foraging benefits of cover crops. We also have a lot to learn about the positive economic domino effects that happen when more farmers use cover crops.”

Researchers will present their results in two webinars, co-hosted by NWF and Practical Farmers of Iowa:
